Neither the Altar nor the Courthouse was a "Centre" of Goverment, they were just associated with it, why would the Altar come with Code of Laws?
Consider it a Codification of State Religious power (and those are Centers of government... if not in the civ sense that a Palace is)

Then how come the Mausoleum comes when you get Constituation, like the Jail, India would have had Musoleums way before the Constituation and the Constitution has nothing to do with Mausoleums.
Consider it advanced form of Nationalism (or a Codification of it)
[Constitution has nothing to do with Jails either, except possibly limiting them, and Currency is not necessary for Marketplaces, etc.]

Are you sure it dosn't mean simply the rate at which your town grows? I could be wrong, but I don't know why it dosn't simply say "Increases Great People Birth rate".
"Birth rate" has always meant Great People (there was confusion when Civ 4 was first coming out about Pacifism and Philosophical)

Grocers are way too early, Supermarkets are not too late.
For REALISM.. Supermarkets are just Right (time wise ... realistically a Mall is a Modern Marketplace, there is rarely a food market [except restaurants and 'specialty foods'....and specialty foods: Spices, Sugar, Wine, Fruit does tie into a Grocer more than a Supermarket: Cow, Pigs, Sheep, Deer ])
For Game Balance... a Later UB is a disadvantage and they figured that making it too late would make America too weak. (of course for all I know they might change it after further Balancing to place it with Supermarket and make it more like the Russian Research Institute... (give it a +25% Culture and +50% Gold, +2 Happiness, and the "Hit Bonus")
